Decreasing order of stability of following alkenes is (i) CH_(3)-CH=C

1.	Decreasing order of stability of following alkenes is (i) CH_(3)-CH=CH_(2) (ii) CH_(3)-CH=CH-CH_(3) (iv) CH_(3)-underset(CH_(3))underset(\|)(C)=CH-CH_(3) (iv) CH_(3)-overset(CH_(3))overset(\|)(C)=overset(CH_(3))overset(\|)(C)-CH_(3)
Answer» (i)gt(II)gt(iii)gt(iv) (iv)gt(iii)gt(ii)gt(i) (iii)gt(ii)gt(i)gt(iv) (ii)gt(iii)gt(iv)gt(i) Solution :Higher the NUMBER of `alpha-H`,more the hyperconjugating STRUCTURES, more the stability of the COMPOUND.
